In the evenings, at home, with a drink.
Now that I'm used to nice studio monitors and a subpac I don't get much enjoyment out of listening on headphones at work (too many interruptions, can't feel the bass) or in the car (my stock speakers suck).
I used to listen to podcasts and mixes all day long. I agree if the music is really good it can be distracting (producer mindset), and if it's cliché / average, I'd rather have peace & quiet.
